Pampa Sur Project – Strong Ag-Sb-As Geochemical Anomalies Defined
- Definition of two significant trends with broadly coincident surface colluvial arsenic, antimony and silver anomalies - the typical geochemical expression of El Penon style low-sulphidation epithermal precious metals veins. - A separate, large, surface colluvial pH anomaly suggesting the presence of acid from oxidizing sulphide mineralization in the underlying bedrock, coincident with a surface colluvial molybdenum anomaly.
The clear anomalies defined by Iron Creek’s work will be followed up with geophysical survey lines, probably CSAMT, in order to better define specific mineralized structures and veins in the underlying bedrock, ahead of drill testing (CSAMT has proven successful at detecting narrow quartz veins and similar structures at the Yamana’s El Penon and Fortuna deposits).
Iron Creek is exploring the Pampa Sur property for epithermal gold and silver mineralization of El Penon/Fortuna and Guanaco types, and also for possible porphyry copper mineralization. The project is located approximately 40km south-southwest of Yamana’s El Penon and Fortuna deposits (+6 million oz gold and +185 million oz silver), and immediately south of Iron Creek’s Pampa Buenos Aires project which is being explored in joint venture with Andina Minerals.
Geological Setting of Pampa Sur -------------------------------
The property is largely covered by post-mineral gravels with sparse outcropping Palaeocene-age volcanic rocks towards the southwest of the property area. The property is cut by strands of the DFZ, which defines the structural grain of the project area.

Work Completed To Date ----------------------
Geological and float mapping and sampling were carried out in conjunction with colluvial and soil pH & ICP geochemical survey programs in three phases. The first sampling phase, between
In early 2008 Argali Geofisica Chile E.I.R.L. conducted ground magnetic surveys on a portion of the Pampa Sur property with a line spacing of 50m and readings acquired as a continuous profile on E-W lines. A total of 920 line kilometers of data were acquired.
Results to Date ---------------
Results from the colluvial and soil geochemical programs are extremely encouraging. As can be seen from the accompanying maps on Iron Creek’s website, largely coincident arsenic (refer to link # 1 below), antimony (link # 2) and partially coincident silver (link # 3) geochemical anomalies occur to the east of the DFZ along an approximately 7km long by 1-2km wide zone that trends north-northwest. This is a significant As-Sb-Ag anomaly, with the three metals that are commonly associated with low-sulphidation precious metals veins of the El Penon type – the main target type sought on the property. The zone is open to the north-northwest (onto Iron Creek and Andina Minerals’ Pampa Buenos Aires property) and to the south-southeast.
A second, smaller, but very intense coincident arsenic, antimony and silver anomaly occurs to the west of the DFZ (links # 1-3 below). This anomaly trends approximately north – south and is about 2.5km long by 0.5km wide, although arsenic anomalies continue more than 2km further to the south. It is broadly coincident with a number of quartz float occurrences.
Other smaller anomalies of one or more of these three key indicator metals occur within the property, and may prove to be significant.
Additionally, a large surface colluvial low pH anomaly has been detected in the NW corner of the property coincident with a surface colluvial molybdenum anomaly. The pH anomaly suggests that oxidizing sulphides – related to mineralization in the underlying bedrock – may be present below the colluvial cover (link # 4, link # 5). However, the exact significance of these coincident anomalies remains to be determined.
Other, narrow pH anomalies likely represent underlying mineralized structures or veins in the bedrock.

Geochemical samples are collected in accordance with accepted industry standards and best practices. Iron Creek carries out its own in-house pH measurements on colluvial and soil samples and applies standard protocols as part of the quality control methodology. Samples are then submitted to ALS Chemex Laboratories in La Serena,
